Enrichment Overview
Definition
of Environmental Enrichment
Enrichment is a
dynamic process for enhancing animal environments within the context of the
animalsŐ behavioral biology and natural history. Environmental changes are made
with the goal of increasing the animalŐs behavioral choices and drawing out
their species-appropriate behaviors, thus enhancing animal welfare (1999 AZA
Behavior Scientific Advisory Group).
Individuals
or Populations?
When
considering animal welfare and environmental enrichment, it is critical to
remember that both are individual-based. While animal caretakers and managers
are often concerned with populations, enrichment and welfare are not –
what is beneficial to one individual may not be for another.
Environmental
Enrichment Plans
At The Shape of Enrichment, Inc., we feel there are some
principles that are critical to achieving successful and efficient enrichment
plans.
Enrichment
plans should be holistic. To ensure that we consider all
aspects of the environment, we recognize 5 Categories of Enrichment:
Social, Cognitive, Physical, Sensory, and Food. These categories are not
mutually exclusive. Each category should be represented appropriately in an
animalŐs enrichment plan.
Enrichment
plans should be goal-driven. Behavioral goals should be determined to direct
the enrichment strategies and schedules for an animal. The goals may be general
(e.g. increase exploration) or specific (e.g. encourage olfactory
investigation). There may be multiple goals for a given animal, and there may
be multiple enrichment strategies offered.
Enrichment
plans should be assessed both initially and periodically throughout the year. The method of
assessment may vary but the intent is to determine if a new enrichment strategy
is meeting your behavioral goal, and if it continues to do so over time. If a
new enrichment strategy is not meeting the goal (or if it has ceased to do so
over time), modifications should be explored.
To ensure that enrichment plans are goal-oriented, tested,
and assessed, we encourage the use of a planning protocol. Several have been
developed and are in use today. For its simplicity and flexibility, we
recommend the Shape Planning
Flow Chart. Another excellent method is S.P.I.D.E.R.
